The phase equilibria in the Cu-Fe-Zr ternary system was experimentally investigated by optical microscopy, electron probe micro-analyzer and x-ray diffraction on the equilibriated alloys. Three isothermal sections of the Cu-Fe-Zr ternary system at 1000, 1100 and 1200 C were experimentally determined, and no ternary compound was found in this system. The further result in the present work shows that the Fe23Zr6 phase in the Cu-Fe-Zr ternary system is an equilibrium phase rather than oxygen-stabilized phase.
